ABSTRACT

The present invention is directed to benzamide containing compounds which inhibit the P2X7 Receptor.

FIELD OF THE INVENTION

The present invention is directed to novel compounds which inhibit the P2X₇ receptor. Separate aspects of the invention are directed to pharmaceutical compositions comprising said compounds and uses of the compounds to treat pain, inflammation, neurological disorders, or neuropsychiatric disorders.

BACKGROUND ART

The purinergic 2X₇ (P2X₇) receptor is a ligand-gated ion channel which is activated by extracellular ATP and is present on a variety of cell types, including microglia in the central nervous system and other cells involved in inflammation and immune system function. The P2X₇ receptor has been shown to have a role in cytolysis in the immune system (Surprenant, et al. Science, 272, 735-41, 1996), and is involved in activation of lymphocytes and monocyte/macrophages leading to the increased release of pro-inflammatory cytokines (e.g., TNFα and IL 1β) from these cells (Ferrari, et al. Neuropharmacol, 36, 1295-301, 1997).

Studies have shown that inhibiting P2X₇ receptor activation in situations of inflammation (e.g., rheumatoid arthritis and other autoimmune diseases, osteoarthritis, asthma, chronic obstructive pulmonary disease and inflammatory bowel disease) or interstitial fibrosis results in a therapeutic effect (DiVirgilio, et al. Drug Dev Res, 45, 207-13, 1998). These and other studies indicate that P2X₇ receptor antagonists may find use in the treatment and prophylaxis of pain, including acute, chronic and neuropathic pain (Chessel, et al, Pain, 114, 386-96, 2005).

Inhibiting P2X₇ activation may also diminish or reduce cell death caused by prolongation of activated P2X₇ receptors, indicating a potential therapeutic intervention for said antagonists in nervous system injury or degeneration (Sperlagh, et al., Progress in Neurobiology, 7, 327-346, 2006). Vianna, et al. (Epilepsia, 43, 27-229, 2002) also revealed a potential role for P2X₇ receptors in the pathogenesis of epilepsy. Interestingly, because of the P2X₇ receptor's role in microglia activation and proliferation in the central nervous system (CNS), a self-propagating cycle of neuroinflammation and neurodegeneration results from P2X₇ receptor activation in areas of the brain (Monif, et al, J Neurosci, 29, 3781-91, 2009).

Thus, P2X₇ receptor antagonists, particularly small molecules with sufficient brain-penetrable properties, are desirable as useful agents for therapeutic intervention in the central nervous system for treating pain, inflammation, neurological and neurodegenerative disorders, neuropsychiatric disorders, or other disorders for which the reduction or otherwise stabilization of pro-inflammatory cytokines is beneficial. The present invention fulfills this need, and provides further related advantages.

SUMMARY OF THE INVENTION

An objective of the present invention is to provide compounds that inhibit P2X₇ receptors. Accordingly, the present invention relates to compounds of Formula I.

This example illustrates representative assays for use in evaluating the test compounds for antagonist activity. Compounds of the present invention were tested in vitro for their ability to act as antagonists to the P2X₇receptor.

Screening assays to determine P2X₇ receptor antagonism are well known to the person skilled in the art. Functional assays, such as second messenger assays, and cytokine measurement assays done in vitro are also well known in the art and may be used to assess the specific binding and cellular activity of P2X₇ receptor compounds.

In Vitro Assay Example

Cell culture: 293 HEK cells, stably transfected with plasmids capable of expressing human P2X₇ receptor, were cultured by standard methods. Cells were plated to cell density of approximately 15,000 cells/well in 384-well assay plates (50 μl/well) with 1.5% low serum media (DMEM, 1.5% BCS, 1% L-glut (2 mM), 1% P/S).

293 HEK cells, stably transfected with plasmids capable of expressing rat or mouse P2X₇ receptor, were cultured by standard methods. Cells were plated to cell density of approximately 15,000 cells/well in 384-well assay plates (50 μl/well) with 1.5% low serum media (DMEM, 1.5% FBS, 1% L-glut (2 mM), 10 mM HUES, 1% P/S). Cells were plated 24 hours prior to assay. Cells expressing human, rat or mouse P2X₇ receptor were assayed in the following manner.

Fluorescent Imaging Plate Reader (FLIPR) assay: Briefly, 293-human or mouse P2X₇ stable cells were incubated in sucrose buffer, pH 7.4 [KCl (5 mM), NaH₂PO₄.2H₂O (9.6 mM), HEPES (25 mM), sucrose (280 mM), glucose (5 mM), CaCl₂ (0.5 mM), and probenecid (0.1425 g in 3 mL 1N NaOH was added for 500 mL solution)] in 384-well plates.

293-rat P2X₇ stable cells were incubated in HHPB (pH 7.4) [consisting of Hank's BSS (1×); HEPES (pH 7.4) (20 mM) (Sigma); probenecid (0.710g/5 mL 1N NaOH) (Sigma); and BSA (0.05%) (Roche) which was added after the pH had been adjusted] in 384-well plates. Fluo-4 NW dye mix (Molecular Probes, Inc., Eugene, Oreg., USA) was prepared in buffer (see manufacturer's instructions). Cell plates were removed from the 37° C. incubator, the media discarded and then 30 μL of dye was added to each well. Plates were placed in the 37° C., non-CO₂ incubator for 30 minutes and then room temperature for 30 minutes.

Two sets of drug plates were prepared: A) Mixtures of compound plus agonist were prepared as follows, in order to determine dose response: BzATP: 11 point ½ log, diluted in buffer, starting from 1 mM. Testing compounds: 11 point ½ log, diluted in 2% DMSO buffer starting from 10 μM. B) Agonist only mixture was prepared with BzATP at a single concentration in buffer (concentration determined by dose response).

Compound mixtures (A) were added to assay plates containing cells and placed at room temperature for 30 minutes, then BzATP (B) was added. Fluorescence was read using the Tetra FLIPR® (Molecular Devices, Inc., Sunnyvale, Calif., USA) and IC₅₀ values were calculated by standard methods to determine antagonist activity.

Assay for stimulating IL1β release from THP-1 cells: THP-1 cells (The Global Bioresource Center; ATCC #: TIB-202™ were differentiated by incubation with 10 ng/mL IFN-gamma (Sigma, Cat#: I3265) in T150 plates, at a cell density of 0.5 E⁶cells/mL, in RPMI1640 media (ATCC, Cat#30-2001) with 10% FBS and 1% P/S for 48 hours. The cells then were stimulated with 100 ng/mL LPS (Sigma, Cat#: L4516) in serum free CTL Test media (Sigma Cat#: CTLT-005), without L-glutamine and antibiotics, for 3 hours. Test compounds (antagonists) were added and incubated for 30 minutes. BzATP (at final concentration of 1 mM) was added and incubated for 30 minutes.

Cell plates were centrifuged at 3000 rpm for 5 minutes and the supernatants were immediately collected for AlphaLISA® immunoassay (PerkinElmer Inc., Waltham, Mass., USN Catalog No. AL220C) or aliquoted and stored at <−20° C. The AlphaLISA® immunoassay was performed according to the manufacturer's instructions.
